Revert "Updated jQuery Form Plugin from v2.17 to v2.36"

This reverts commit 72037d61436978daa1edbd19d52b7e6fc6ae1fa8.

Until some of the XHR notice related bugs are sorted out in Opera and
Chromium, reverting back to the previous version. It throws slightly
less errors. XHR file attachments is still a bit problematic in
Opera 10.10/Ubuntu, Opera 10.10/Windows, and Chrome 4/Ubuntu. But this
revert will at least allow regular XHR notices to work okay in Opera
and Chromium.

Standards suck!

- * jQuery Form Plugin

-	Usage Note:
-	-----------
-	Do not use both ajaxSubmit and ajaxForm on the same form.  These
-	functions are intended to be exclusive.  Use ajaxSubmit if you want
-	to bind your own submit handler to the form.  For example,
-
-	$(document).ready(function() {
-		$('#myForm').bind('submit', function() {
-			$(this).ajaxSubmit({
-				target: '#output'
-			});
-			return false; // <-- important!
-		});
-	});
-
-	Use ajaxForm when you want the plugin to manage all the event binding
-	for you.  For example,
-
-	$(document).ready(function() {
-		$('#myForm').ajaxForm({
-			target: '#output'
-		});
-	});
-
-	When using ajaxForm, the ajaxSubmit function will be invoked for you
-	at the appropriate time.

+    Usage Note:  

+    -----------

+    Do not use both ajaxSubmit and ajaxForm on the same form.  These

+    functions are intended to be exclusive.  Use ajaxSubmit if you want

+    to bind your own submit handler to the form.  For example,

+

+    $(document).ready(function() {

+        $('#myForm').bind('submit', function() {

+            $(this).ajaxSubmit({

+                target: '#output'

+            });

+            return false; // <-- important!

+        });

+    });

+

+    Use ajaxForm when you want the plugin to manage all the event binding

+    for you.  For example,

+

+    $(document).ready(function() {

+        $('#myForm').ajaxForm({

+            target: '#output'

+        });

+    });

+        

+    When using ajaxForm, the ajaxSubmit function will be invoked for you

+    at the appropriate time.
